the issue with the USA is that they've already got something like 200 million guns circulating the country already, which makes an outright gun ban there kinda useless. But its very clear based on the data that countries with less guns have way less gun violence. Look to the UK and Australia. Very safe countries with strict gun control. Plus, the U. S. constitution clearly states that the guns should be in the hands of a well regulated militia. The implementation of the second amendment in reality though seems very far from its intended purpose.
